Abstract: Technology to increase the amount of hearing aid gain attainable in the high frequencies without additional acoustic feedback is being developed by hearing aid manufacturers. Aided soundfield thresholds and subjective appraisal were used to assess digital feedback suppression as incorporated in the Danavox I45 DFS, high power; post aural hearing aid. This preliminary study looked at whether extra gain, without acoustic feedback, could be made available between 2KHz and 4KHz and whether this could provide benefit in speech perception and other; everyday auditory experiences. The soundfield measurements typically, indicated better thresholds at 4KHz (p < 0.05) and less obviously at 3KHz. Not all participants demonstrated overall improvement. High frequency benefit as a result of this technology cannot be assumed and good fitting, high quality earmoulds remain essential for children using high power hearing aids.
